Welcome. Good introduction. We're here to help.
An 80 is a great vehicle and it matters little really whether it's auto or manual. The later UK 24v engined models only came in manual but you can get imports in auto. They're all 80's. All good. But the trick is finding a good one. Any good one will do. As has been said before, if you limit yourself to it being something exact you could be looking a long time. (Like me, I want a blue, 97, manual, low mileage, one owner, dealer maintained with only delivery mileage on the clock) Certainly don't be put off by an auto. I have a manual and an auto and they both lovely to drive.
There are some mechanical bits that will need attention on just about anything that you buy but if you've had Landies for 10 years you'll know all about that. There are a couple of bodywork warning spots too but nothing terminal.
Oh, we kinda have rules on here which are unwritten but we'd like to think that we honour. If you post a link and say I have seen this, what do you think? We don't rush off and steal from under your feet! if it's an pen add don't be surprised though if someone else is already looking. They go fast, so be prepared to move.
